I have a serious problem with my display of pages within the page-administration in my wordpress backend.
All of a sudden, most of my pages simply disappear in the “attribute” part of the menu where the pulldown menu is located with all the other pages. I am pretty sure it has something to do with the database, because I checked all plugins and updated my wordpress installation to the newest version. Old database backups work fine, but there are so many changes since than, that I need to repair my actual database.
I just wonder where does the backend pulls the information for displaying all the possible parent sites from the database?
